EZPECIPICATIQN forming part of Letters Patent No. 346,296, dated July13, 1886.

Application filed November 12, 1885.

To aZZ whom it may concern.-

Be it known that I, AUGUsT FRIEBERT- SHAUSER, of Sand usk y, in thecounty of Erie and State of Ohio, have invented certain new and usefulImprovements in Pocket-Knives; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such aswillenable others skilled in the art to which it pertains to make anduse the same.

My invention relates to improvements in pocket-knives, in which thespring back is dovetailed to the sides of the handle, the object beingto provide a cheap and strong attachment for these parts.

In the accompanying drawings, Figure 1 is a side elevation of atwo-bladed knife embodying my invention. Fig. 2 is a plan view of theback of the knife. Fig. 3 is a side view ofthe handle and a view inperspective of the spring back, showing the parts detached. Figs. land 5are respectively views of the side and back of a four-bladed knifeembodying my invention.

The sidesA of the handle are of metal, and have corresponding slots, (1,in the back edge, the end walls of which are undercut, as shown. Thespring-back B is provided with laterallyprojeeting tongues or wings b,with beveled edges, and made to fit the slots a, the parts, whenassembled, forming dovetails. If there i are one or more blades at eachend of the knife, the tongues b should be located about in thecenterlengthwise of the knife, and may be narrow; but if there areblades only at one end of the knife the tongues b may be located welltoward the opposite end, and should be of resist the torsionalconsiderable width to Serial No. 182,515. (No model.)

strain on the tongues caused by the action of the spring-back. sides Alaterally at each of the handle and secures the parts, and one or bothof these rivets serve as'pivots for the blades, according as there areblades at one or both ends of the knife. In case there are blades onlyat one end of the knife, the rivet a passes inside of the spring-back,the latter at this end curving up and corresponding to the shape of thesides to form a better finish. As there are no rivets passing throughthe spring-back, the latter is madeof a flat steel plate only thickenough to give the required stiffness to the sprin In addition to themetal sides A, of course any outside covering may be had forornamentation or otherwise; but inthe absence of any such covering thesides A may be polished and plated, if preferred, so as to presentafineappearance. In this manner a strong, durable, and finely-finished knifemay be made at a small initial cost.

What I claim is- In a pocket-knife, a, spring-backhavinglaterally-projecting tongues with beveled edges, in combinationwith the sides of'the handle, the latter having recesses or gains on theunder edge to receive the tongues of the spring-back, the engaging partsforming a dovetail, substantially as described, and for the purposes setforth.

In testimony whereof I sign this specification, in the presence oftwowitnesses, this 21st day of August, 1885.
